title: Detection of small genotypic changes in Escherichia coli by pyrolysis mass spectrometry.
abstract: Pyrolysis mass spectrometry (Py-MS) has been used to discriminate between four very closely related strains of Escherichia coli; a parent strain UB5021 and three derivatives each containing one of the antibiotic resistance plasmids, pBR322, pACYC184 or R388.
